"Intelligent design" refers to a scientific research program as well
as a community of scientists, philosophers and other scholars who seek
evidence of design in nature. Through the study and analysis of a system's
components, a design theorist is able to determine whether various natural
structures are the product of chance, natural law, intelligent design,
or some combination thereof.

For example, consider Mount Rushmore:

The pattern of the rocks in the talus slopes below the faces is due
primarily to chance and natural law. The pattern of erosion alongside
the faces is due primarily to natural law and chance. The pattern of
the presidents' faces is due primarily to intelligent design.
